SPJ

What SPJ does

SPJ is a Tokyo-based private AI company founded in 2017 that develops and sells AI chatbot systems, AI-powered retail assistants, and a portfolio of domain-specific AI modules — all built on its proprietary "Neurox" natural language processing engine. The company's core technical specialization is Japanese-language NLP combined with big data analytics, with Neurox providing high-precision intent interpretation, multilingual dialogue support (English, Japanese; Chinese and Korean in preparation), real-time learning, and deployment flexibility (cloud or on-premises). Beyond chatbots, SPJ has expanded into adjacent AI capabilities including CRNN-based OCR for invoice and document recognition, AI-powered proofreading, automated FAQ generation from CRM and call logs, purchase data analysis and product recommendation engines, recruitment entry-sheet analysis, and survey text mining for product development positioning.

The business operates through a multi-channel model: direct enterprise sales of customized Neurox deployments, OEM/API licensing of the Neurox engine to partners including NEC Nex Solutions, cloud service co-development with inet (株式会社アイネット) for SMB reach, and IT catalog distribution through Netland covering approximately 100,000 SMB prospects nationwide. Revenue streams include Neurox cloud subscriptions, custom AI solution projects, professional consulting, AI technical training seminars (¥4,800 general / ¥1,000 student), and licensing royalties. Customer segments span enterprise contact centers, retail (notably MONCEAU FLEURS Ginza deployment), recruitment (Musashino), chemical regulatory compliance (Techno Hill), and content publishing.

Notable certifications include ISMS (ISO/IEC 27001), Privacy Mark, METI business continuity plan certification, and Tokyo Metropolitan Government business innovation plan approval. SPJ holds partnerships with Digital Attendant (DA社) for speech-enabled AI staff, Edia for AI car navigation, and joint research relationships with Ledge and WebRider for AI proofreading. The company is self-funded with no external investment rounds recorded and operates from Chiyoda-ku, Tokyo under current Representative Director Mizutani Yoshikazu.
